 Water (And Other Vapor) Sorption
Complete moisture adsorption isotherms can be performed on your samples anywhere from 12oC to 85oC. Two or more isotherms (at different temperatures) can be used to yield adsorption enthalpy. Please note, even hydrophobic samples can adsorb moisture from the vapor phase due to capillary condensation forces! Ideal for investigating coatings, deliquescence, etc. Organic vapors can be used to study differences between polar/non-polar surfaces.
